Here is the call graph for this function:

intel_pt_find_overlap()

unsigned char* intel_pt_find_overlap	(	unsigned char *	buf_a,
		size_t	len_a,
		unsigned char *	buf_b,
		size_t	len_b,
		bool	have_tsc,
		bool *	consecutive
	)

intel_pt_find_overlap - determine start of non-overlapped trace data. : first buffer : size of first buffer : second buffer : size of second buffer : can use TSC packets to detect overlap : returns true if there is data in buf_b that is consecutive to buf_a

When trace samples or snapshots are recorded there is the possibility that the data overlaps. Note that, for the purposes of decoding, data is only useful if it begins with a PSB packet.

Return: A pointer into from where non-overlapped data starts, or + if there is no non-overlapped data.
